The CP violation parameter η+− is determined through the eigentime-dependent asymmetry in the rates of initially tagged K0 and K0 decaying to π+π−. The obtained values are |η+−| = (2.312 ± 0.043stat. ± 0.030syst. ± 0.011τs) × 10−3 and Φ+− = 42.7° ± 0.9stat.° ± 0.6syst.° ± 0.9Δm° with Δ = (527.4 ± 2.9) × 107h̵gs−1 measured in the same experiment using the semileptonic decay channel.
